This fix is an attempt to fix issue raised in #28005 where
`docker stats` on Windows shows Linux headers if there is
no containers in stats.
The reason for the issue is that, in case there is no container,
a header is faked in:
https://github.com/docker/docker/blob/v1.13.0/cli/command/formatter/formatter.go#L74-L78
which does not know OS type information (as OS was stored with container stat entries)
This fix tries to fix the issue by moving OS type information
to stats context (instead of individual container stats entry).
Additional unit tests have been added.
This fix fixes#28005.

This change does some minor cleanups in the
cli/command/container package;
- sort imports
- replace `fmt.Fprintf()` with `fmt.Fprintln()` if no formatting is used
- replace `fmt.Errorf()` with `errors.New()` if no formatting is used
- remove some redundant `else`'s

While looking into `docker stats <c1> <c2> ...` I noticed that
the error output is quite long, especially if there are multiple errors:
```sh
ubuntu@ubuntu:~/docker$ docker stats nofound
: Error response from daemon: No such container: nofound
ubuntu@ubuntu:~/docker$ docker stats nofound foo bar
: Error response from daemon: No such container: nofound, : Error response from daemon: No such container: foo, : Error response from daemon: No such container: bar
```
There are several issues,
1. There is an extra `: ` at the beginning. That is because if container is not found,
the name will not be available from the daemon.
2. Multiple errors are concatenated with `, ` which will be quite long.
This fix:
1. Only prient out the error from daemon.
2. Multiple errors are printed out line by line.
Below is the new output:
```sh
ubuntu@ubuntu:~/docker$ docker stats nofound
Error response from daemon: No such container: nofound
ubuntu@ubuntu:~/docker$ docker stats nofound foo bar
Error response from daemon: No such container: nofound
Error response from daemon: No such container: foo
Error response from daemon: No such container: bar
```

As for `ps`, `images`, `network ls` and `volume ls`, this makes it
possible to define a custom default format.

The formatter.ContainerStats struct exposes its Mutex.
This is a bad design and should be fixed.
To fix that, I separated the statistics
attributes from ContainerStats to StatsEntry and
hid the mutex. Notice that the mutex protects both
the `err` field and the statistics attributes.
Then, implemented SetStatistics, SetError, GetStatistics
and GetError to avoid races.
Moreover, to make this less granular, I decided to
replace the read-write mutex with the regular mutex and
to pass a StatsEntry slice to formatter.ContainerStatsWrite
